SQL Server Cannot open user default database Login Failed

As a Lync support person you might need to handle some SQL issues. Most of the cases you want to move database here and there because of the disk space issue or for proper allocation of disk. Here i faced a challenge while doing LCSLOG database movement from one disk to another Disk.

I have detached the database and copy the database in another disk after that i was not able to login to SQL management studio. I was getting "Cannot open user default database.Login Failed error".

I thought my SQL got corrupted ,After lot of search i got the solution like below.

Open SQL Managemnet Studio
Select options tab

Now change the connect to database to master or any available database on your setup

 

Now click on connect and it will successfully log you in. Once you login in the system run following statement for your username and it should fix your problem. Make sure to replace [test] with your username and master with yourdatabase name.

ALTER LOGIN [username] WITH DEFAULT_DATABASE = master
GO

Intermittent AOL PIC issue in Lync

Initially when we configured Lync fo Public IM communication we have recieved lot of omplaints from users related IM failed when the communicate with AOL users.After Lot of touble shooting found one solution and it helped me to resolve our issue.

In order to resolve this, you need to change the Cipher Suite order used by Windows such that TLS RSA with RC4 128 MD5 is tried first.
In order to change the Cipher Suite order, do the following on your Access Edge server:

1. Launch the Group Policy Object Editor using: Start --> Run -> gpedit.msc
2. Within the Group Policy Object Editor, traverse down to; Computer Configuration --> Administrative Templates --> Network --> SSL Configuration
3. Click on SSL Configuration, and then double-click on SSL Cipher Suite Order (by default, the SSL Cipher Suite Order is set to "Not Configured")
4. Select the “Enabled” radio button, and in the in the SSL Cipher Suites text box, copy the entire string into Notepad.
5. Find  TLS_RSA_WITH_RC4_128_MD5, in the list and cut and paste it to the first item in the list.  (Be sure to take the trailing comma with it so you don't end up with a ",," in the list)
6. Paste the newly-formatted string back into the text field in the GPO Editor, click OK
7. Restart (reboot) the Lync Access Edge server for these changes to take effect.

Thanks for below Link.

What's New Lync 2013

Below is the some major feature about Lync 2013 Preview

• Full IPv6 support
• VDI plugin, allowing full A/V support in virtual desktop environments
• H.264 SVC codec support
• Skype federation support
• Persistent chat (or group chat) becomes a "full-fledged" Lync service, not just a bolted-on add-on
• Audio and video added to Lync Web App
• Consolidation of roles; no separate server role needed for monitoring and archiving
• Hybrid deployments of on-premises and Lync Online cloud servers now supported (this capability is called "hybrid voice")
• Support for M-N trunk routing, plus support for inter-trunk routing. Lasko explains: "This feature allows Lync to act as an intermediary between two or more different phone systems. For example, Lync can accept calls from one PBX, and pass the call through to another PBX. This can be very useful in larger environments and allows Lync to be the backbone of a corporate telephone network."
• Support for a unified contact store, with information maintained in MIcrosoft Exchange Server 2013, enabling users to access/manage contacts from Lync 2013 Preview, Outlook or Outlook Web App

Remove + from FromURI or RequestURI in Lync 2010

Some of the call manager will not suppot when lync initiate call with +symbol in both to and From URI's(E.164).In such cases You can remove the + from lync side while sending to the call manager or gateway.

ToURI + you can strip from the trunk configuration using GUI.Like below.

But to remove + from FromURi there is  no option available in GUI mode.Format will be something  like this.from<sip:+12345@.....>.In this case gateway or call manager may not acept such request.

This option you can change using powersehell script.Run the get-cstrunkconfiguration.You will get output like below.

Here in the image highlighted seeting we need to make it as true.So it will remove + before sending to Call manager or gateway.Command will be like this.Set-CStrunk configuration -identity "test" RemovePlusFromUri $true.Now the Header wil be like From<Sip:12345@.....>to<.....>
